✦ Synopsis

There are many steady states in collisionless plasmas. Their dynamical stability has been one of the main interests in the study of plasmas. In one-dimensional space, we discover some new types of stable equilibria by constructing new invariants to the Vlasov-Maxwell system. These stable equilibria include new flat-tail solutions that connect different densities, pressures, and strengths of constant magnetic fields at x = ±∞.
